PABLO FERRARI

BACKEND DEVELOPER

Professional Summary

Backend developer with 10+ years building systems across industries that have almost nothing in common — real estate portals, gaming platforms, EdTech tools, hotel dashboards, telecom microservices, fintech infrastructure. Different stacks, different problem domains, different teams. The constant is that I've always owned things end-to-end: design, build, deploy, maintain.

In my current role at Unicity I went deep on global payment systems — integrating 10+ providers across NA, EU, and APAC, implementing 3DS v2, and recovering over $850K in failed transactions. Payments is one chapter of the story. In 2021 I joined Crowdability (NYC) as their first internationally located hire — no playbook existed for it. I've migrated legacy codebases nobody wanted to touch, stood up CI/CD pipelines where there were none, and built MVPs from a blank file.

Proud marathon runner. Long-term thinking comes with the territory.
